Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 468990, here are decompositions:

7 + 468983 = 468990
17 + 468973 = 468990
23 + 468967 = 468990
37 + 468953 = 468990
97 + 468893 = 468990
101 + 468889 = 468990
103 + 468887 = 468990
107 + 468883 = 468990

Showing the first eight; more decompositions exist.
